Your NVMe Had Been Syz'ed

Overview: NVMe is a game-changing storage technology that delivers unparalleled speed and performance, making it crucial for cloud environments where intensive workloads and scalability, demand rapid data access and processing. In recent years, NVMe-oF/TCP support was added to the Linux kernel, and with it a new attack surface was unlocked. In this talk, we will present how we added the NVMe-oF/TCP subsystem support to syzkaller, the famous fuzzer, by modifying both the Linux kernel and syzkaller. Also, the multiple vulnerabilities found after running the modified fuzzer will be presented as well.
